SK Hynix Sheds 11.5% as Chinese DRAM Rival’s $8.6B IPO and Global Chip Sell-Off Collide
Published on 07/16/2026 at 16:38 | Redaktion boerse-global.de
An 8% surge on Wednesday proved fleeting. SK Hynix plunged 11.53% on Thursday in Seoul, wiping out almost all of the previous session’s gains and closing at 1,842,000 Won. The stock has now lost 38.33% from its 52-week high of 2,987,000 Won set on June 25, and over the past seven days alone it has shed 15.74%.
The sell-off had two distinct triggers that converged in the same trading session. Overnight in the United States, a broad rout in semiconductor shares saw Micron Technology tumble 8%, Intel lose more than 4%, and AMD and Lam Research each slide roughly 3%. That weakness swept into Asia at the open. But in Seoul, a second, company-specific shock added to the pressure: Chinese DRAM maker ChangXin Memory Technologies (CXMT) confirmed plans for an initial public offering in Shanghai worth $8.6 billion, with trading scheduled to begin on July 27, 2026. SK Hynix currently commands 29% of the global DRAM market and 58% of the high-bandwidth memory segment — the fast-growing chip type central to artificial intelligence workloads. A well-capitalized new entrant threatens to flood the market and squeeze margins.
The broader Korean market absorbed heavy collateral damage. Samsung Electronics fell more than 7%, Seoul Semiconductor dropped over 5%, and other chip-exposed names followed suit. The KOSPI index opened 4.45% lower at 6,960.50 and extended losses to an intraday low of 6,753 — a decline of more than 6% from the prior close. The drop was severe enough to trigger the market’s 37th sidecar of 2026, a five-minute pause on programmatic sell orders after KOSPI 200 futures tumbled over 5%.
Should investors sell immediately? Or is it worth buying SK Hynix?
Further complicating the outlook, the Bank of Korea raised its benchmark interest rate by 25 basis points to 2.75%, the first hike since early 2023, citing persistent inflation of 3.2%. Higher rates disproportionately weigh on high-growth technology stocks, adding a macroeconomic headwind to the sector-specific turbulence.
Yet the sell-off is unfolding against a backdrop of resilient fundamentals. ASML, the Dutch lithography giant, lifted its 2026 revenue forecast for the second time to a range of €43-45 billion, above analyst expectations, and flagged plans to accelerate EUV machine production. SK Hynix itself completed a record $26.5 billion Nasdaq ADR listing just last week, on July 10, drawing strong initial demand. Analysts remain broadly constructive on the memory cycle. Kim Sunwoo of Meritz Securities told Reuters that DRAM suppliers are currently meeting only 75-80% of demand, and that coverage could slip to roughly 60% by 2027, tightening supply and supporting higher prices. HSBC has also pointed to improving profitability at AI services companies as a reason to expect sustained cloud investment.
Geopolitical crosscurrents add another layer of uncertainty. US lawmakers are pressing the Biden administration to bar domestic companies from buying memory chips made by Chinese suppliers such as CXMT and YMTC, aiming to reduce reliance on Chinese technology in AI infrastructure. Meanwhile, Beijing imposed new export controls on helium, an essential gas for extreme-ultraviolet lithography, effective July 10. A disruption to helium supply chains could hamper fabrication schedules industry-wide.
Technically, SK Hynix’s decline has been brutal but may not be exhausted. The relative strength index stands at 40.5 — below the neutral 50 level but still above the 30 threshold that typically signals oversold conditions. Annualized volatility has surged to 127.39%, underscoring the whipsaw nature of recent trading. Despite the pullback, the stock remains up 172.63% year to date. The memory squeeze that analysts expect to intensify into 2027 offers a structural bull case, but for now, every piece of news out of China and every tremor in the global chip complex keeps the share price on edge.
